PROBLEM TO BE SOLVED: To provide an operating microscope with a main objective (main objective lens) that extends along an objective plane and is penetrated by a binocular main observer beam path and a binocular co-observer beam path.SOLUTION: The operating microscope has the main objective 1 that extends along the objective plane and is penetrated by the binocular main observer beam path and the binocular co-observer beam path. The binocular main observer beam path has two main observation pupils 3A, 3B in the objective plane with centers on a first virtual straight line 7. The binocular co-observer beam path has a pair of co-observation pupils 5A, 5B in the objective plane with centers on a second virtual straight line 9. The first and second virtual straight lines 7, 9 intersect. The co-observer beam path can be displaced with respect to the main observer beam path, so that the angle between the first and second virtual straight lines 7, 9 changes. The center point 6 between the co-observation pupils 5A, 5B in the objective plane displaces when there is a change in the angle between the first and second virtual straight lines 7, 9.COPYRIGHT: (C)2011,JPO&INPIT【課題】対物面に沿って延び、且つ双眼主観察者ビーム経路及び双眼補助観察者ビーム経路が通る主対物(主対物レンズ)を備えた手術用顕微鏡を提供する。【解決手段】手術用顕微鏡は、対物面に沿って延び、且つ双眼主観察者ビーム経路及び双眼補助観察者ビーム経路が通る主対物1を備える。双眼主観察者ビーム経路は対物面に一対の主観察瞳3A,3Bを有し、それらの中心は第一の仮想直線7上にある。双眼補助観察者ビーム経路は対物面に一対の補助観察瞳5A,5Bを有し、それらの中心は第二の仮想直線9上にある。第一及び第二の仮想直線7,9は交差する。補助観察者ビーム経路は主観察者ビーム経路に対して変位可能であり、これにより第一及び第二の仮想直線7,9間の角度が変化する。第一及び第二の仮想直線7,9間の角度が変化すると、対物面における補助観察瞳5A,5B間の中心点6が変位する。【選択図】図3
